udatetime dependency error occur while installing rets-python library

[sohaibbt]

Hi, i am facing below error while intalling this libary on local machine however this library works fine on Google colab.
please can you help me to fix this on my local machine.

building 'udatetime.rfc3339' extension
  error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

Maybe fixed with #67

@nsinkov How is this one? udatetime on version 0.0.17 seems to fix installation on linux/ubuntu for python 3.9+, however according to #59 @janwelten still have an issue on windows...

Can we bump version of rets-python, so we can install that at least on linux?

In my humble opinion there should be no python-impure compiled dependency when this library is not speed critical and especially dependency that seems to be no longer maintained...
it's better to have an (IO bound) library that is easy to use (currently rets-python is uninstallable on python 3.9+ which is quite opposite of easily usable) than faster but with a lot of effort to make it work

This is still an issue

@wimby, hi, unfortunately we will not have the cycles to look at this in the near term. Would you be able to submit a PR?

[bperry]

@nsinkov The version just needs bumped and published. You guys have already changed the version dependency of udatetime to 0.0.17 which will fix this. However the version on pypi doesn't reflect that yet.

[wimby]

@nsinkov yes, right now it's about bumping and publishing rets-python (latest version on pypi is not installable on any python 3.9+ and current master as is will work on linux python 3.9+)

long term solution that will work on windows could be getting rid of udatetime (e.g. #65) or fixing udatetime on windows (they claim it's currently POSIX only library, not sure how hard is it to make it cross-platform though)
